CS51031

Fast PFET Buck Controller

The CS51031 is a switching controller for use in DC–DC

converters. It can be used in the buck topology with a minimum

number of external components. The CS51031 consists of a V

monitor for controlling the state of the device, 1.0 A power driver for

controlling the gate of a discrete P–channel transistor, fixed frequency

oscillator, short circuit protection timer, programmable soft start,

precision reference, fast output voltage monitoring comparator, and

output stage driver logic with latch.

The high frequency oscillator allows the use of small inductors and

output capacitors, minimizing PC board area and systems cost. The

programmable soft start reduces current surges at start up. The short

circuit protection timer significantly reduces the duty cycle to

approximately 1/30 of its cycle during short circuit conditions.

The CS51031 is available in 8 Lead SO and 8 Lead PDIP plastic

packages.
